For a tape A." wide and 0.02" thick, and a leather strip about 0.04" thick, these beveled surfaces may be at an angle of about to the grain side 19 of the leather strip. The strips out from the hide may prior to beveling them be joined together in a known manner involving skiving their ends and cementing such skived ends together to produce strips of great length, say strips 1,000 yards long.

The beveled leather strip 9 may be placed in a roving can (Fig. l) and be drawn therefrom, by passing it between the cooperating presser rolls 21 and 29, over a platen 3| in opposed relation to the brush 33 of a cement fountain 35, for coating the flesh side of the leather strip, including the beveled surfaces 2! thereof, with suitable cement. This cement, for example, may be rubber cement consisting of a solution of natural or synthetic-rubber in naphtha such as is commonly employed in shoe making. The textile strip or tape H, as shown, is drawn, by the same presser rolls 2! and 29, from a roll 31 of the tape mounted on an arbor 39, through a bath 41 of the same character as that employed for coating the leather strip 9, this bath acting preferably to coat both sides of the tape and more or less to impregnate it with the cement.

In its passage from the cement fountain 35 to the rolls 2'! and 29 the leather strip 9 is shown as passing several times about the widely spaced rotary reels 43, while the textile strip or tape H in its passage from the bath 4| toward the rolls 2'! and 29 is shown as passing around the widely spaced roll sets 45, in each case sufficiently to dry the cement to render it tacky to enable the tape and leather stri to be cemented together by a pressing operation.

Just prior to passing between the rolls 2'! and 29 the textile and leather strips are received by a guide 4! best illustrated in Fig. 8, the guide being shown on an exaggerated scale in Fig. 1. This guide comprises a sheet metal bod t8 the edges of which as they extend toward the rolls 2'! and 29 are tapered toward each other as indicated at 5| (Fig. 8), these edges integrally carrying the folded over portions 53. The edge of the guide 41 adjacent the rolls 2? and 29 is placed preferably as close to those rolls as possible, and presents an opening of such shape as will apply the textile strip or tape II to the portion 23 of the flesh side of the leather strip, as shown in Figs. 4 and 5, and at the same time fold or bend the beveled portions of the leather strip upwardly in closely adjacent relation to the edges of the textile strip and fold or bend the free edge portions of the bevels slightly inwardly to cause them to lie above the exposed side of the textile strip adjacent its edges as shown in Fig. 5, the opposite edges of the opening through which the two strips pass being preferably rounded, as shown at 51, so as to cause the opposite edges of the leather strip at its grain side to be rounded. On leaving the guide 41 the two strips pass between the presser rolls 2'! and 29, the pressure exerted by the rolls on the two strips being regulated in a known manner by mechanism (not shown), and one roll being a driven and the other an idle roll. As shown, the roll 29 is provided with the opposite peripheral end flanges 59, between which flanges the peripheral portion of the roll 21 fits. As shown in Fig. 6, the face 6! of the upper roll 21 is formed at its opposite edges with the filleted corners 63, while the face 65 of the lower roll 29 is formed at its opposite edges with the complementary filleted corners 61, so as to form a roll pass corresponding to the cross-sectional shape of the finished stripping shown by Fig. '7. When entering the roll pass just described the textile and leather strips are disposed with relation to each other as shown in Fig. 5, and in passing through the roll pass the beveled edge portions of the leather strip are forced from their position shown by Fig. 5 to their position shown by Fig. '7, as a result of which the textile strip or tape II is deformed by the beveled edge portions of the leather strip to form the beveled edges I3 of the textile strip, and because the textile strip is more or less absorbent with respect to cement and therefore more or less impregnated with such cement the textile strip maintains its beveled edges, while the beveled edge portions of the leather strip being molded by the presser rolls to the shape shown by Fig. '7 maintain that shape, the presser rolls acting to squeeze the two strips together so that they are cemented together, and the exposed faces of the stripping except at its rounded edges are fiat. The resulting stripping exteriorly has finished rounded edges 59, and the textile strip fitting a dovetail channel in the leather strip acts to prevent separation of the two strips when the strippin is applied to a shoe.

It will be understood that Within the scope of the appended claims wide deviations may be made from the form of the invention described without departing from the spirit of the invention.
